ADJUSTABLE BAND.

Application filed August 5, 1922. Serial 1T0. 579,808.

To all whom it may concern:

Be it known that I KNUT E. ENGLUND, a citizen of the Unite 'States, andresiding at Brooklyn, in the county of Kings and State of New York, haveinvented certain new and useful Improvements in Adjustable Bands, ofwhich the following is a specification, such as will enable thoseskilled in the art to which it appertains to make and use the same.

This invention relates to adjustable bands and particularly to devicesof this class designed for use in securing suitably flexible or othertubings in connection with suitable supports, and the object of theinvention is to provide a device of the class specified which is soconstructed as to permit of the mounting of said band in connection witha suitable support by hand, and by the use of a suitable tool, such as ascrew driver, when excess pressure is required; a further object beingto provide improved means for retaining the separate parts or endportions of the band together and for reinforcing and strengthening oneend portion of the band; and with these and other objects in view theinvention consists in a band of the class and for the purpose specifiedwhich is simple in construction, efiicient in use, and which isconstructed as hereinafter described and claimed.

The invention is fully disclosed in the following specification, ofwhich the accompanying drawing forms a part, in which the separate parts0 my improvement are designated by suitable reference characters in eachof the views, and in which Fig. 1 is a transverse sectional View througha flexible tubing mounted on a suitable support, and indicating themethod of mounting one of my improved bands thereon.

Fig. 2 is a view similar to 1 but showing the parts in a differentposition.

Figs. 8 and 4 are plan views of the construction shown in Fig. 2 viewedfrom different angles.

Fig. 5 is a sectional detail View of one end portion of a modified formof band which I may employ.

Fig. 6 shows a planand sectional view of one end portion of anothermodified form of band; and,

Fig. 7 shows a plan and sectional view of one end portion of stillanother modified form of band.'

Theinvention shown and described herein is an improvement on that shownand described in a patent granted to me on the 2nd day of May, 1922, No.1,414,731 in which a tool of spec1fic construction was employed forcoupling the end portions of the band together. The present inventionrelates to a band of the class under consideration which is soconstructed asto avoid the necessity of the use of a specific tool andin connection with which a screw driver or similar tool may be used forthe purpose of securing the end portions of the band together.

For the purpose of illustratin one use of my improvement, I have shownin Figs. 1 to 4, a part of a pipe 10 on which is mounted a rubber tubingor hose 11 which is secured on thepipe by one of my improved bands 12.In the construction shown in Figs. 1 to 4 inclusive, the band 12 comrises two ring members 13 closed or .joined shownat 14 and said endportion of the band is provided with a plurality of spaced teeth orprojections 15, which are substantially arc-shaped in form in crosssection and which are formed by roviding a number of transverse cuts int e band 12 or the end portion 14 thereof, and pressing one edge of saidend portion adjacent to each cut outwardly to form the teeth orprojections 15. It will be noted that the teeth or p-rojections 15 arejoined to the body of the end portion 14 of the band through sections ofsubstantially the same area as the width of said teeth or projections toform a strong and durable projecting member. The other end portions ofthe ring members 13 are open and are joined and reinforced by atransverse plate or clip member 16 preferably of greater thickness thanthe material employed in the band 12 and the end portions of the ringmembers 13 are secured to the plate or clip member 16 by welding,riveting, or in any other desired manner.

The plate or clip member 16 is provided with a downwardly or inwardlydirected and preferably pointed lip or flange 17 which overlaps the endsof the ring members 13, and the lip or flange 17 is adapted to interlock.with the teeth or projections 15 to securely hold the end portions ofthe band together. The plate or clip member 16 is at one end as alsoprovided with an upwardly or outwardly directed part 18 which forms afinger piece to facilitate the attachment of the band to a suitablesupport by hand, and to also form a bearing against which a suitabletool may be placed and operate in moving the plate or clip member intoposition to engage the teeth or projections 15.

It will also be noted that the end portion 14 of the band is providedwith projecting members 19 which are adapted to extend beneath the otherend portion of the band or the ring members 13 to form a continuousannular compression body of said band, when mounted on a suitablesupport, and the members 19 are preferably slightly tapered. t

In the use of my improved-band 12 as shown in Figs. 1 to 4 inclusive, itwill be noted that the band is applied to the tubing 11 by hand, whichresult is accomplishedby pressure of the thumb upon thepro ectmg part 18of the member 16 and 1t stronger pressure is required for securelysealing the connection between the tubing 11 and the pipe 10, a screwdriver or other tool is placed beneath the member 16 and in engagementwith one of the teeth'or projections 15 beneath such member as shown inFig. 1 of the drawing, after which the screw driver or other tool ismoved to the ri ht to advance the end portion of the ban 12-, providedwith the member 16, longitudinally of the other end portion thereof sothat the lip or flange 17 will engage another tooth or projection asillustrated in Fig. 2 of the drawing and this operation will be repeateduntil the band 12 has been securely wrapped around the tubing 11. Inorder to remove the band, all that is necessary to do'is to place ascrew driver or other tool beneath the end portion of the band providedwith the clip member 16 to pry the same u wardly and the end portions ofthe band Wlll then spring apart.

In Fig. 5 of the drawing, I have shown a slight modification of theconstruction shown in Figs. 1 to 4 inclusive in which I substitute forthe plate or clip member 16., a similar part 20 which is formed integralwith the end portion of the band by folding said end portion backwardlyupon the band, and fashioning the folded part 21 to form a lip 17similar to the lip 17 in Figs. 1 and 2 of the drawing, and the part 18is formed from the free end portion of the band. In this construction,the band 12 is also made solid instead of being provided with theseparate ring member 13, and an aperture 22 is provided in the band injuxtaposition to the part 18 to permit of the insertion of a screwdriver or other tool. The other end portion of the band will be of thesame construction as shown in Figs. 1 to 4 inclusive.

In Fig. 6 of the drawing, I have shown another modification in which thepart 18 is formed by cutting a section 23 from a solid band and bendingit upwardly and downwardly and this operation forms an aperture 24 inthe band 1n juxtaposition to the part 18, the same as in Fig. 5 of thedrawing. With this construction, the free end portion of the band isbent downwardly to form the lip or flange 17.

The construction shown in Fig. 7 is prac tically the same as that shownin Fig. 6 with the exception that the part 18 is formed by pressing orfashioning the material of the band outwardly to form said part and inthis construction, an aperture 25 is also provided in juxtaposition tothe part 18, and the free end portion of the band is proyided with a lip17 as in Fig. 6 of the drawmg.

In all of the forms of construction shown, the part 18 of the bandserves as a finger piece and backing against which a suitable tool mayoperate in mountingthe band in a suitable support, and this structurealso serves to reinforce and strengthen the band at this point and itwill be noted that the parts 18 in Figs. 6 and 7 of the drawing will beriveted, welded or otherwise secured together. It will be noted that myinvention is not necessarily limited to the specific use herein set outas the same may be used for many other purposes and constructed oflighter or heavier material, depending upon the us to which the band isto be adapted and while I have shown certain details of construction forcarrying my invention into efl'ect, it will be noted that I am notnecessarily limited to these details and various changes therein, andmodifications thereof may be made within the scope of the appendedclaims without departing from the spirit of my invention or sacrificingits advantages.
